CHECK-ROW MARKER.

Application filed April 11,

To all whom it may concern:

Be it known that I, PETER E. WIs'rnANn, a citizen of the United States, residing at Galva, in the county of Henry and State of Illinois, have invented a new and useful (ilheck-Row Marker, of which the following is a specification.

The subject of this invention is a check row marker adapted for cooperative asso ciation with a planter, upon which it may be mounted, and the objects of the invention are, first, to provide a marker which may be swung to operative position from either side of the planter, and which has novel pivotal connection with the planter, second, to provide a marker which automatically moves from operative to inoperative position, and vice versa, at the end of each row, and third, to provide a simple, cheap, and efficient marker of the character set forth.

with these and such other objects in view as may hereinafter more fully appear, my invention consists in the noval arrangement and construction of parts set forth in the following description, more particularly pointed out in the claims, and one practical and preferred form of which is shown in the accompanying drawings, wherein Figure 1 is a plan View of a planter with a marker, constructed in accordance with my invention, in place thereon.

Fig. 2 is a broken detail showing, in rear elevation, the marker arm in operative position, the supporting bracket being shown in vertical section.

Fig. 3 is a broken detail showing, in side elevation, the marker arm in inoperative position, the supporting bracket being shown in section.

Fig. 4 is a perspective view of the bracket.

Fig. 5 is a perspective view of the plate for protecting the buttons of the check wire.

Referring to the drawing by numerals The marker is adapted to be attached to any usual form of planter, such as that shown herein, wherein wheels 1, with their axles 2, form the support for the main frame of the machine. The frame has side beams 3 to the forward ends of which a cross member 4: is attached, said cross member forming a support for the seed hoppers 5.

The beams 3 extend rearwardly beyond the wheels 1, and to the beams, adjacent their rear ends, is attached a bar 6, arranged transversely of the planter. To each end of Specification of Letters Patent.

Patented July 3, 1H1 t. Serial No. 161,249.

The angled or bent end 3), of a marker arni 1.0, extends through the hub H, in which it is loosely mounted; allowing the arm ll) a pivotal movement about the hub and at the same time, a vertical oscillation. This oseil latory movement is illustrated most clearly by the dotted lines in Fig. A marker 11 is adjustable on each arm 10, to which it is clamped, when adjusted, by the screw bolt 12. A collar 13, formed with an eye 14-, is secured to each marker arm 10, and a cable 15 is connected at each end to an eye 1i, and passes over suitable guides, not shown, seoured to the cross member t, or other suitable portion of the planter.

Secured to each end. of the bar 6 is a plate 16, formed with an extended end 17, which is adapted to partially overlie the cone 8 for the purpose of preventing the end of the arm 10 from being jolted from its seat therein. Each plate 16 is also formed with a curved edge 18 which acts as a protector for the buttons 19 (only one of which is shown), of the check wire 20.

As appears most clearly in Figs. 2 and 3, the major axis of a horizontal cross section of the hub 8 would lie in a direction transverse of the planter. This formation allows greatest play of the marker arm when in operative position, and causes the end 9 to contact the interior side wall of the hub as the arm swings to inoperative position, thus materially assisting the automatic action o f the arms.

In use the device operates as followsz When planting is started, the arm 10, on the side toward which the planter is working, is swung outwardly to operative position, thereby causing, through the connecting cables 15, the opposite arm 10 to swing to inoperative position. The seeder is then drawn across the field in the usual manner, the marker 11, which is in operation, leav ing a furrow which indicates the position of the next row to be planted. When the end of a row is reached and the planter turned, the arm 10, which has been in oper ative position, will be swung toward its inoperative position, because of the contact of the marker with the ground. This inward swing of one arm 1.0 will, allow the other arm, which has been in inoperative position, to swing outwardly, under the action of gravity, and assume its operative position.

Having described my invention, What I claim as new and desire to secure by Letters Patent, is

1. A check row marker including in combination, a planter and a transverse bar thereon, a conical hub secured to each end of the bar, a marker arm loosely pivoted in each hub, a marker secured to each arm, and a cable connecting the arms.

2. A check row marker including, in combination, a planter and a transverse bar thereon, a conical hub secured to each end of the bar, the major axis of a l'mrizontal cross section of the hub lying" transversely of the planter, marker arms each having a bent end which passes through a hub, a marker on each arm, and a flexible connection between the arms.

3. A check row marker including, in com Copies of this patent may be obtained for five cents each, by addressing the thereon, a conical hub secured to each end of the bar and disposed at an angle thereto,

a marker arm loosely pivoted to each hub, a marker secured to each arm, and a cable connecting the arms.

a. A check row marker including, in combination, a planter and a transverse bar thereon, a hub secured to each end of the bar and provided With a conical opening, a marker arm loosely pivoted to each hub, a plate secured to each end of the transverse bar and overlying the hub, and a curved edge formed on each plate.

In testimony that I claim the foregoing as my own, I have hereto aiiixed. my signature in the presence of two witnesses.
